Prices fell 1.4 per cent from October, which was the largest month-on-month fall since June 2020.
And annual house price growth saw a “sharp slowdown”, the building society says, falling to 4.4 per cent now from 7.2 per cent in October.
Last month the government’s official forecaster – the Office for Budget Responsibility – predicted that house prices would drop 9.0 per cent over the next two years.
Robert Gardener, Nationwide’s chief economist, says: “While financial market conditions have stabilised, interest rates for new mortgages remain elevated and the market has lost a significant degree of momentum. Housing affordability for potential buyers and home movers has become much more stretched at a time when household finances are already under pressure from high inflation.
“The market looks set to remain subdued in the coming quarters. Inflation is set to remain high for some time and Bank Rate is likely to rise further as the Bank of England seeks to ensure demand in the economy slows to relieve domestic price pressures.
“The outlook is uncertain, and much will depend on how the broader economy performs, but a relatively soft landing is still possible.
“Longer term borrowing costs have fallen back in recent weeks and may moderate further, especially if investors continue to revise down their expectations for the future path of Bank Rate. Given the weak growth outlook, labour market conditions are likely to soften, but they are starting from a robust position with unemployment still near 50-year lows.
“Moreover, household balance sheets remain in good shape with significant protection from higher borrowing costs, at least for a period, with around 85 per cent of mortgage balances on fixed interest rates. Stretched housing affordability is also a reflection of underlying supply constraints, which should provide some support for prices.”
